Thanks for all the replies. I guess I wasn't very clear about the cleanse because I hadn't really read the program guide. It is eating, and fiber supplements, and green food supplements and protein shakes and lots of whole food supplements.
I meant I was "eating" now as a final period of enjoyment before I begin a whole new lifestyle and new and improved body! I plan to start it Friday so that I can be evaluated on the final day as directed.
The more web searches I did based on my symptoms, sounds like I am in adrenal burnout which makes sense with my "superwoman" lifestyle: RN, wife, 4 kids under 7, 10 yrs of marriage to a recovering self centered man, and completely deficient in self care.
So, I do embark on this journey, willingly, but with great hope that eventually, I will feel like myself again, whomever she might be.
